Bug 391831

I realized that {python,perl,ruby} bindings are in libzypp-bindings package, however only ruby bindings are enabled. Why is that?

how is that critical? 

I thought this was not intentional and some zypp utilities depend on these bindings.

removing needinfo

I did some research and the main problem is with variable collisions. I added some rename rules for SWIG, so SWIG does now generate code for python and perl (it didn't before). But now it fails to compile. I'm attaching the patch against libzypp-bindings in Factory and build failure logs for python-zypp and perl-zypp.

Re-enabled the binding in libzypp-bindings-0.4.6.

Bindings are not build because they require libzypp-devel >= 5.2.1

and this version of libzypp is not built in Factory because of error described below - I suggest trying to update also libsatsolver from SVN.

Fixed by last commit from mls.

I installed python-zypp and all of its dependencies from Factory:

boost-1.34.1-53.x86_64
gd-2.0.36.RC1-27.x86_64
graphviz-2.20.2-8.x86_64
graphviz-gd-2.20.2-8.x86_64
graphviz-gnome-2.20.2-8.x86_64
libqdialogsolver1-1.2.0-17.x86_64
libzypp-5.3.0-2.x86_64
python-zypp-0.4.6-9.x86_64
satsolver-tools-0.10.2-2.x86_64
yast2-ncurses-2.17.3-6.x86_64
yast2-ncurses-pkg-2.17.5-5.x86_64
yast2-pkg-bindings-2.17.2-5.x86_64
yast2-qt-pkg-2.17.3-5.x86_64
zypper-0.12.0-12.x86_64

and now I get:

$  echo 'import zypp;' | python
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib64/python2.5/site-packages/zypp.py", line 7, in <module>
    import _zypp
ImportError: /usr/lib64/python2.5/site-packages/_zypp.so: undefined symbol: _ZN4zypp8RepoInfo14defaultPrioityEv

Clearly something went wrong during update (I believe that packages are built correctly), but I can not figure what and how.

This symbol is indeed an undefined static method due to a typo (defaultPrio(R)ity). Ruby didn't mind this.
(we urgently need time and testcases for the bindings)

Fixed in libzypp-bindings-0.4.7.
